Slackware's traceroute(8) command is a very useful network diagnostic tool. traceroute displays each host that a packet travels through as it tries to reach its destination. You can see how many “hops” from the Slackware web site you are with this command:
% traceroute www.slackware.com |
Each host will be displayed, along with the response times at each host. Here is an example output:
% traceroute www.slackware.com traceroute to www.slackware.com (204.216.27.13), 30 hops max, 40 byte packets 1 zuul.tdn (192.168.1.1) 0.409 ms 1.032 ms 0.303 ms 2 207.171.227.254 (207.171.227.254) 18.218 ms 32.873 ms 32.433 ms 3 border-sf-2-0-4.sirius.com (205.134.230.254) 15.662 ms 15.731 ms 16.142 ms 4 pb-nap.crl.net (198.32.128.20) 20.741 ms 23.672 ms 21.378 ms 5 E0-CRL-SFO-03-E0X0.US.CRL.NET (165.113.55.3) 22.293 ms 21.532 ms 21.29 ms 6 T1-CDROM-00-EX.US.CRL.NET (165.113.118.2) 24.544 ms 42.955 ms 58.443 ms 7 www.slackware.com (204.216.27.13) 38.115 ms 53.033 ms 48.328 ms |
traceroute is similar to ping in that it uses ICMP packets. There are several options that you can specify with traceroute. These options are explained in detail in the man page.
